The Koombooloomba Dam is a concrete gravity dam with a controlled spillway across the Tully River, located west of Tully and south, southeast of Ravenshoe in Far North Queensland, Australia.

Built for the purpose of hydroelectric power generation, the dam creates the reservoir, Lake Koombooloomba.

The reservoir has a catchment area of 163 square kilometres (63 sq mi) with a controlled concrete spillway that releases up to 1,240 cubic metres per second (44,000 cu ft/s).
